ABSTRACT:
An add-drop optical circuit is provided comprising: a first multiplex/demultiplexer for demultiplexing a composite optical signal having a plurality of channels, a second multiplex/demultiplexer for multiplexing a plurality of signals into a composite optical signal; waveguides disposed between the first demultiplexer and the second multiplexer/demultiplexer; and a plurality of 11/2.times.2 optical switches coupled to at least some of the waveguides for adding and dropping optical signals, the optical switches substantially preventing optical signals from propagating from an add port to drop port.
